DESIGNATION AND RANK. The designation of such series of the Preferred Stock shall be the Series B Convertible Preferred Stock, par value $0.01 per share (the "SERIES B CONVERTIBLE PREFERRED STOCK"). The maximum number of shares of Series B Convertible Preferred Stock shall be sixty thousand (60,000) shares. The Series B Convertible Preferred Stock shall rank senior to the common stock, par value $.01 per share, of the Company (the "COMMON STOCK"), and to all other classes and series of equity securities of the Company which by their terms do not rank senior to the Series B Convertible Preferred Stock, including but not limited to the Series A Junior Participating Preferred Stock. Subject to Section 3 hereof, the Board of Directors may by resolution issue and designate additional series or classes of preferred stock which may rank senior to, junior to, or on parity with the Series B Convertible Preferred Stock as to dividends or the distribution of assets upon liquidation, dissolution or winding up, redemption rights and the other rights preferences and privileges of such preferred stock. Shares ranking senior to, on a parity with, and junior to the Series B Convertible Preferred Stock as to dividends or the distribution of assets upon liquidation, dissolution or winding up, as the case may be, are hereinafter referred to as "SENIOR STOCK," "PARITY STOCK" and "JUNIOR STOCK," respectively. 2. DIVIDENDS. In the event any dividend or other distribution payable in cash or other property is declared on the Common Stock (excluding any dividend or other distribution for which adjustment to the Conversion Ratio is provided by Section 5(e) hereof), each holder of shares of Series B Preferred Stock on the record date for such dividend or distribution shall be entitled to receive on the date of payment or distribution of such dividend or other distribution the same cash or other property which such holder would have received, if on such record date such holder was the holder of record of the number of shares of Common Stock into which the shares of Series B Preferred Stock then held by such holder are then convertible. 3. VOTING RIGHTS. (a) CLASS VOTING RIGHTS. The Series B Convertible Preferred Stock shall have the following class voting rights (in addition to the voting rights set forth in Section 3(b) hereof). So long as at least ten percent (10%) of the original issuance of the Series B Convertible Preferred Stock remain outstanding, the affirmative vote or consent of the holders of at least two-thirds (2/3) of the shares of the Series B Convertible Preferred Stock outstanding at the time, given in person or by proxy, either in writing or at a meeting, shall be necessary for effecting or validating: (i) the increase in the authorized or issued amount of Series B Convertible Preferred Stock, or the authorization, creation or issuance of shares of any class or series of stock, or any security convertible into shares of any class or series of stock, ranking senior to or on parity with the rights, preferences, privileges and powers of, or restrictions provided for the benefit of, the Series B Convertible Preferred Stock; (ii) any amendment, alteration or repeal of any of the provisions of the Certificate of Incorporation or By-Laws of the Company, or this Certificate of Designation, so as to adversely affect any right, preference, privilege or power, or restriction provided for the benefit of, the holders of the Series B Convertible Preferred Stock; and (iii) any corporate or shareholder action which reclassifies any outstanding shares of the Company into shares having a preference or priority right to receive dividends or assets senior to or on a parity with the preference of the Series B Convertible Preferred Stock. (b) GENERAL VOTING RIGHTS. Except with respect to transactions upon which the Series B Convertible Preferred Stock shall be entitled to vote separately as a class pursuant to Section 3(a) above and except as otherwise required by Delaware law, the Series B Convertible Preferred Stock shall vote together with the Common Stock on any matter submitted to a vote of the stockholders (whether at a meeting or by written consent). For the purposes of any matter in which the Series B Convertible Preferred Stock votes together with the Common Stock, each share of Series B Convertible Preferred Stock shall have the number of votes equal to the number 2 of shares of Common Stock then issuable upon its conversion into Common Stock pursuant to Section 5 hereof. 4. LIQUIDATION RIGHTS. (a) LIQUIDATION PREFERENCE. In the event of the liquidation, dissolution or winding up of the affairs of the Company, whether voluntary or involuntary, after payment or provision for payment of the debts and other liabilities of the Company, the holders of shares of the Series B Convertible Preferred Stock then outstanding shall be entitled to receive, out of the assets of the Company whether such assets are capital or surplus of any nature, an amount equal to eighty dollars ($80) per share (the "LIQUIDATION PREFERENCE AMOUNT") of the Series B Convertible Preferred Stock plus any declared but unpaid dividends before any payment shall be made or any assets distributed to the holders of the Common Stock or any other Junior Stock. If, following payment in full of Senior Stock, the assets of the Company are not sufficient to pay in full the Liquidation Preference Amount plus any declared but unpaid dividends payable to the holders of outstanding shares of the Series B Convertible Preferred Stock and any series of preferred stock or any other class of stock on a parity, as to rights on liquidation, dissolution or winding up, with the Series B Convertible Preferred Stock, then all of said assets will be distributed among the holders of the Series B Convertible Preferred Stock and the other classes of stock on a parity with the Series B Convertible Preferred Stock, if any, ratably in accordance with the respective amounts that would be payable on such shares if all amounts payable thereon were paid in full. All payments for which this Section 4(a) provides shall be in cash, property (valued at its fair market value as determined by the Company's independent, outside accountant) or a combination thereof; PROVIDED, HOWEVER, that no cash shall be paid to holders of Junior Stock unless each holder of the outstanding shares of Series B Convertible Preferred Stock has been paid in cash the full Liquidation Preference Amount plus any declared but unpaid dividends to which such holder is entitled as provided herein. After payment of the full Liquidation Preference Amount plus any declared but unpaid dividends to which each holder is entitled, such holders of shares of Series B Convertible Preferred Stock will not be entitled to any further participation as such in any distribution of the assets of the Company. (b) LIQUIDATION, DISSOLUTION AND WINDING UP.

(c) NOTICES. Written notice of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, stating a payment date and the place where the distributable amounts shall be payable. The written notice required by this Section 4(c) shall be deemed given if delivered personally or by facsimile or three (3) business days 3 following being mailed by certified or registered mail, postage prepaid, return-receipt requested, addressed to the holder of record at its address appearing on the books of the Company, no less than forty-five (45) days prior to the payment date stated therein. 5. CONVERSION. The holder of Series B Convertible Preferred Stock shall have the following conversion rights (the "CONVERSION RIGHTS"): (a) RIGHT TO CONVERT. Each share of Series B Convertible Preferred Stock shall be convertible, at the holder's option, at any time or from time to time, into a number of fully paid and nonassessable shares of Common Stock at a ratio of ten (10) shares of Common Stock for each share of Series B Convertible Preferred Stock (the "CONVERSION RATIO"). The Conversion Ratio is subject to adjustment as hereinafter provided. (b) MECHANICS OF CONVERSION. To exercise the conversion privilege set forth in Section 5(a) hereof, the holder of shares of Series B Convertible Preferred Stock shall surrender the shares to be converted, accompanied by instruments of transfer satisfactory to the Company and sufficient to transfer the Series B Preferred Stock being converted to the Company free of any adverse interest, at the principal offices of the Company or any of the offices or agencies maintained for such purpose by the Company ("CONVERSION AGENT") and shall give written notice (by registered or certified mail, overnight courier or hand delivery) to the Company or such Conversion Agent that the holder elects to convert such shares. Such notice shall also state the name or names, together with address or addresses, in which the certificate or certificates for shares of Common Stock which shall be issuable on such conversion shall be issued. As promptly as practicable after the surrender of such shares of Series B Preferred Stock as aforesaid, the Company or its Conversion Agent shall issue and deliver to such holder a certificate or certificates for the number of full shares of Common Stock issuable upon the conversion of such shares in accordance with the provisions hereof. New certificates shall be issued representing the balance of any shares of Series B Preferred Stock covered by certificates surrendered for conversion in any case in which fewer than all of the shares of Series B Preferred Stock represented by a certificate are converted. Each conversion pursuant to Section 5(a) hereof shall be deemed to have been effected immediately prior to the close of business on the date on which the shares of Series B Preferred Stock shall have been so surrendered and such notice shall have been received by the Company as aforesaid. (c) FRACTIONAL SHARES. No fractional shares of Common Stock shall be issued upon conversion of the Series B Preferred Stock. In lieu of any fractional shares to which the holder would otherwise be entitled, the Company shall pay cash equal to such fraction multiplied by the then fair market value of one share of Common Stock, as determined in good faith by the Board of Directors of the Company. (d) HOLDER OF RECORD. The person or persons in whose name or names any certificate or certificates for Common Stock shall be issuable upon a conversion of the Series B Convertible Preferred Stock shall be deemed to have become the holder or holders of record of the Common Stock represented thereby at the effective date of such conversion, unless the stock transfer books of the Company shall be closed on such date, in which event such conversion shall be deemed to have been effected immediately prior to the open of business on the next succeeding day on which such stock transfer books are open, and such person or persons shall be 4 deemed to have become such holder or holders of record of the Common Stock represented thereby at the open of business on such later day. (e) ADJUSTMENTS OF CONVERSION PRICE. (i) ADJUSTMENTS FOR STOCK SPLITS AND COMBINATIONS. If the Company shall, at any time or from time to time after the date of filing of this Certificate of Designation, effect a stock split of the outstanding Common Stock, the Conversion Ratio shall be proportionately increased. If the Company shall at any time or from time to time after the date of filing of this Certificate of Designation, combine the outstanding shares of Common Stock, the Conversion Ratio shall be proportionately decreased. Any adjustments under this Section 5(e)(i) shall be effective at the close of business on the date the stock split or combination occurs. (ii) ADJUSTMENTS FOR CERTAIN DIVIDENDS AND DISTRIBUTIONS. If the Company shall at any time or from time to time after the date of filing of this Certificate of Designation, make or issue, or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in shares of Common Stock, then, and in each event, the Conversion Ratio shall be increased proportionately as of the time of such issuance or, in the event such record date shall have been fixed, as of the close of business on such record date, by increasing the Conversion Ratio such that each share of Series B Convertible Preferred Stock shall be converted into ten (10) shares of Common Stock plus the number of additional shares of Common Stock per share of Series B Convertible Preferred Stock that each holder of a share of Common Stock is entitled to receive in payment of such dividend or distribution. (iii) ADJUSTMENTS FOR RECLASSIFICATION, EXCHANGE OR SUBSTITUTION. If the Common Stock issuable upon conversion of the Series B Convertible Preferred Stock at any time or from time to time after the date of original issuance of the Series B Convertible Preferred Stock shall be changed to the same or different number of shares of any class or classes of stock, whether by reclassification, exchange, substitution or otherwise (other than by way of a stock split or combination of shares or stock dividends or distributions provided for in Sections 5(e)(i) and (ii)), then, and in each event, an appropriate revision to the Conversion Ratio shall be made and provisions shall be made (by adjustments of the Conversion Ratio or otherwise) so that the holders of the Series B Convertible Preferred Stock shall have the right thereafter to convert the Series B Convertible Preferred Stock into the kind and amount of shares of stock and other securities receivable upon reclassification, exchange, substitution or other change, which such holders would have received had such holders' Series B Convertible Preferred Stock been converted immediately prior to such reclassification, exchange, substitution or other change, all subject to further adjustment as provided herein. (iv) NO IMPAIRMENT. The Company shall not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith, 5 assist in the carrying out of all the provisions of this Section 5 and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the holders of the Series B Convertible Preferred Stock against impairment. The Company may in its sole discretion make such adjustments in the Conversion Ratio, in addition to those required by paragraphs 5(e)(i), (ii) and (iii) above, as it considers to be advisable in order that any event treated for Federal income tax purposes as a dividend of stock or stock rights shall not be taxable to the recipient. (v) CERTIFICATES AS TO ADJUSTMENTS. Upon occurrence of each adjustment or readjustment of the number of shares of Common Stock issuable upon conversion of the Series B Convertible Preferred Stock pursuant to this Section 5, the Company at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of such Series B Convertible Preferred Stock a certificate setting forth such adjustment and readjustment, showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon written request of the holder of such affected Series B Convertible Preferred Stock, at any time, furnish or cause to be furnished to such holder a like certificate setting forth such adjustments and readjustments, the applicable Conversion Ratio in effect at the time, and the number of shares of Common Stock and the amount, if any, of other securities or property which at the time would be received upon the conversion of a share of such Series B Convertible Preferred Stock. (vi) ADJUSTMENTS FOR CONVERSION SHARES OTHER THAN COMMON STOCK. In the event that at any time as a result of an adjustment made, the holder of any share of Series B Convertible Preferred Stock thereafter converted shall become entitled to receive any shares of the Company other than Common Stock, thereafter the Conversion Ratio of such other shares so receivable upon conversion of any share of Series B Preferred Stock shall be subject to readjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Stock contained herein. (vii) ISSUE TAXES. The Company will pay any and all documentary, stamp or similar issue or transfer taxes payable in respect of the issue or delivery of shares of Common Stock on conversion of shares of the Series B Convertible Preferred Stock pursuant hereto; PROVIDED, HOWEVER, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issue or delivery of shares of Common Stock in a name other than that of the holder of the shares of the Series B Preferred Stock to be converted and no such issue or delivery shall be made unless and until the person requesting such issue or delivery has paid to the Company the amount of any such tax or has established, to the satisfaction of the Company, that such tax has been paid.
